wah- IMPROVEMENT IN BALANCING MILLSTONES.

. n Y The Schedule referred to in these Letters Patent and making part of thevsame.

lo allilzliom 'it may concern.

Bei it known that I, CHARLES V. Fountain', ot Mecbanicstown, inthe county ot' Frederick and State of Maryland, have invented certain new and useful Improvement-s in Mills; and I do hcreby declare that the following isa full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters ot' reference marked thereon which form a part of ,this specilication.

lhe nature ot' my invention consists in a new method of placing the bed or stationary stone in' mills, and also in attaching adjustable balances to thc upper stone or runner bnr.

1n order to enable others skilled in the art to which m'y invention appertains to make and use the same, will now proceed to describe its construction and operation, referring tothe annexed drawings, in which- Figure l is a vertical section of a mill, showing my improvements, and

` Figure 2 is a bottom view of the casing `in which the bed-stone is placed.

A represents the bed-stone or stationary stone, and

B, the upper or runner stone.

Usually the bed-stone is placed solid in the floor, and a casing or boards placed close up to its outer circurnterence. v 'glhis has been l'onud to have many inconveniences well known to all` practical millers, and'V the object otmy invention is to overcome these ditliculties. v

For this purpose the bed-stone A is placed in a box or casing, C, which is raised up trom the door, rest-ing upon'legsD D, as seen in lig. 1. 4

The box or casing C is of larger diameter than the bed-sione, so as to leave a space between the outer circumference ofthe stone and the inner circumference of the casing.

rlhrough the bottom of the box or casing are placed a series ot' Screws, a a, upon which the bed-stone rests, so that the stone can be raised and lowered at will for any desired purpose. This has never been accomplished before, the bed-stone being-heretofore invaribly lixed so to be iunnovable.

lhe bed-stone A is held, and if necessary trammed, by screws, b, passing inward through the 'sides ofthe casing C. The bottom ol' this casing is suitably cnt along its outer circumference, so as to correspond with the space let't between the bed-stone and casing. This can be done in various ways, one form of which is shown in tig. 2.

The runner bur or upper stone is generally prolvided with balances tirmly imbedded in the stone, which balances cannot be moved. I provide the stone with adjustable balances in the following manner:

Around the upper and lower edges ol' the stone B are placed iron bands, d d, to which are, at suitable intervals, secured ears, e e, and in each set of two such ears is secured a bolt or rod, f, provided with screw-threads, said bolts or rods 'running perpendicularly, as seen in tig. 1.

On each of said bolts or rods f is placed a balance,'

I, the rod being screwed through the same. By this means the balances can be carried up' to the upper edge ot' the stone, or down to the lower edge; in tact, can be adj usted in any manner desired.

Having fully described my invention,

What l claim as new, and desire to secure by Letters Patent, i'sy f' The combination of the bands d d, when provided with ears e e, screw-rods fj, and balance-weights i I, when operated by means ot' the nnts g g, all constructed and arranged as herein set forth.A

In testimony that I claim the lforegoing as' my own, I ati'ix my signature in presence ot' two witnesses. l
